In 2014, Fender announced that they were closing the Ovation guitar factory in New Hartford, Connecticut , leaving all production of Ovation guitars overseas. Before that announcement, Fender established a U.S. production of various acoustic guitars in
695-415: A break; the harmony of this two-bar break, the turnaround, can be extremely complex, sometimes consisting of single notes that defy analysis in terms of chords. Much of the time, some or all of these chords are played in the harmonic seventh (7th) form. The use of the harmonic seventh interval is characteristic of blues and is popularly called the "blues seven". Blues seven chords add to the harmonic chord
834-567: A center for electric blues from 1948 on, when Muddy Waters recorded his first success, "I Can't Be Satisfied". Chicago blues is influenced to a large extent by Delta blues , because many performers had migrated from the Mississippi region. Howlin' Wolf , Muddy Waters, Willie Dixon and Jimmy Reed were all born in Mississippi and moved to Chicago during the Great Migration. Their style
973-399: A component of R&B. After World War II, new styles of electric blues became popular in cities such as Chicago , Memphis , Detroit and St. Louis . Electric blues used electric guitars , double bass (gradually replaced by bass guitar ), drums , and harmonica (or "blues harp") played through a microphone and a PA system or an overdriven guitar amplifier . Chicago became

The lyrics often relate troubles experienced within African American society. For instance Blind Lemon Jefferson 's "Rising High Water Blues" (1927) tells of the Great Mississippi Flood of 1927 : Backwater rising, Southern peoples can't make no time I said, backwater rising, Southern peoples can't make no time And I can't get no hearing from that Memphis girl of mine Although
1390-568: A helicopter design company, Kaman Aircraft , in 1945. The Kaman Corporation soon diversified, branching into nuclear weapons testing, commercial helicopter flight, development and testing of chemicals, and helicopter bearings production. In the early 1960s, however, financial problems from the failure of its commercial flight division forced it to expand into new markets, such as entertainment and leisure. Charles Kaman, still an avid guitar player, became interested in making guitars. From 1966 to 2007, Ovation guitars, and later on Adamas guitars, were

#17328484706971668-610: A movement known as the Great Migration . The long boom following World War II induced another massive migration of the African-American population, the Second Great Migration , which was accompanied by a significant increase of the real income of the urban blacks. The new migrants constituted a new market for the music industry. The term race record , initially used by the music industry for African-American music,

Although she admitted being unable to describe the manner of singing she heard, Forten wrote that the songs "can't be sung without a full heart and a troubled spirit", conditions that have inspired countless blues songs. Though the use of the phrase in African-American music may be older, it has been attested to in print since 1912, when Hart Wand 's " Dallas Blues " became
2224-594: A part in early blues, citing Robert Johnson 's " Cross Road Blues " as a "thinly veiled reference to Eleggua , the orisha in charge of the crossroads". However, the Christian influence was far more obvious. The repertoires of many seminal blues artists, such as Charley Patton and Skip James , included religious songs or spirituals. Reverend Gary Davis and Blind Willie Johnson are examples of artists often categorized as blues musicians for their music, although their lyrics clearly belong to spirituals. The blues form
2363-569: A part of ragtime; Handy's signature work was the " Saint Louis Blues ". In the 1920s, the blues became a major element of African American and American popular music, also reaching white audiences via Handy's arrangements and the classic female blues performers. These female performers became perhaps the first African American "superstars", and their recording sales demonstrated "a huge appetite for records made by and for black people." The blues evolved from informal performances in bars to entertainment in theaters. Blues performances were organized by
2502-581: A product. Some industries, such as semiconductor and steel manufacturers, use the term fabrication instead. The manufacturing sector is closely connected with the engineering and industrial design industries. The Modern English word manufacture is likely derived from the Middle French manufacture ("process of making") which itself originates from the Classical Latin manū ("hand") and Middle French facture ("making"). Alternatively,

Apart from guitars , the company currently produces acoustic basses , mandolins and ukuleles . Founder Charles Kaman (1919–2011) developed the first prototypes of the Ovation guitar in 1965–1966. Kaman, an amateur guitarist from an early age, worked on helicopter design as an aerodynamicist at United. Eventually, he founded
2780-419: A recording career that began in 1926 and spanned forty years. These recordings were typically labeled " race records " to distinguish them from records sold to white audiences. Nonetheless, the recordings of some of the classic female blues singers were purchased by white buyers as well. These blueswomen's contributions to the genre included "increased improvisation on melodic lines, unusual phrasing which altered
2919-567: A result, they make only a reactive contribution. Emerging technologies have offered new growth methods in advanced manufacturing employment opportunities, for example in the Manufacturing Belt in the United States. Manufacturing provides important material support for national infrastructure and also for national defense . On the other hand, most manufacturing processes may involve significant social and environmental costs. The clean-up costs of hazardous waste , for example, may outweigh

#17328484706973058-406: A separate genre arose during the black migration from the countryside to urban areas in the 1920s and the simultaneous development of the recording industry. Blues became a code word for a record designed to sell to black listeners. The origins of the blues are closely related to the religious music of Afro-American community, the spirituals . The origins of spirituals go back much further than

Charles Kaman put a team of employees to work to invent a new guitar in 1964. For the project, Kaman chose a small team of aerospace engineers and technicians, several of whom were woodworking hobbyists as well. One of these
3336-450: A thin layer of birch in its Adamas model. The Adamas model dispersed the sound-hole of the traditional soundboard among 22 small sound holes in the upper chamber of the guitar, which Ovation says yields greater volume and further reduces feedback during amplification (pioneered in the Adamas model in 1977). Although the area of the multiple sound holes is equal to the area of a single-soundhole,
3475-581: A wide variety of styles and subgenres. Blues subgenres include country blues , Delta blues and Piedmont blues , as well as urban blues styles such as Chicago blues and West Coast blues . World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience, especially white listeners. In the 1960s and 1970s, a hybrid form called blues rock developed, which blended blues styles with rock music . The term 'Blues' may have originated from "blue devils", meaning melancholy and sadness. An early use of

During the Neolithic period, polished stone tools were manufactured from a variety of hard rocks such as flint , jade , jadeite , and greenstone . The polished axes were used alongside other stone tools including projectiles , knives, and scrapers, as well as tools manufactured from organic materials such as wood, bone, and antler. Copper smelting
3753-449: Is a cyclic musical form in which a repeating progression of chords mirrors the call and response scheme commonly found in African and African-American music. During the first decades of the 20th century blues music was not clearly defined in terms of a particular chord progression. With the popularity of early performers, such as Bessie Smith , use of the twelve-bar blues spread across
3892-519: Is a music genre and musical form that originated amongst African-Americans in the Deep South of the United States around the 1860s. Blues has incorporated spirituals , work songs , field hollers , shouts , chants , and rhymed simple narrative ballads from the African-American culture . The blues form is ubiquitous in jazz , rhythm and blues , and rock and roll , and is characterized by
4031-560: Is a sly wordplay with the double meaning of being " tight " with someone, coupled with a more salacious physical familiarity. Blues songs with sexually explicit lyrics were known as dirty blues . The lyrical content became slightly simpler in postwar blues, which tended to focus on relationship woes or sexual worries. Lyrical themes that frequently appeared in prewar blues, such as economic depression, farming, devils, gambling, magic, floods and drought, were less common in postwar blues. The writer Ed Morales claimed that Yoruba mythology played
4170-502: Is believed to have originated when the technology of pottery kiln allowed sufficiently high temperatures. The concentration of various elements such as arsenic increase with depth in copper ore deposits and smelting of these ores yields arsenical bronze , which can be sufficiently work-hardened to be suitable for manufacturing tools. Bronze is an alloy of copper with tin; the latter of which being found in relatively few deposits globally delayed true tin bronze becoming widespread. During
4309-450: Is characterized by its lyrics , bass lines , and instrumentation . Early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the AAB pattern , consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over

4448-484: Is conventionally defined by the widespread manufacturing of weapons and tools using iron and steel rather than bronze. Iron smelting is more difficult than tin and copper smelting because smelted iron requires hot-working and can be melted only in specially designed furnaces. The place and time for the discovery of iron smelting is not known, partly because of the difficulty of distinguishing metal extracted from nickel-containing ores from hot-worked meteoritic iron. During

Hokum blues celebrated both comedic lyrical content and a boisterous, farcical performance style. Tampa Red and Georgia Tom 's " It's Tight Like That " (1928)
10425-568: The blues in the same year in Missouri ; and W.C. Handy , who first heard the blues in Tutwiler, Mississippi , in 1903. The first extensive research in the field was performed by Howard W. Odum , who published an anthology of folk songs from Lafayette County, Mississippi , and Newton County, Georgia , between 1905 and 1908. The first non-commercial recordings of blues music, termed proto-blues by Paul Oliver , were made by Odum for research purposes at
10564-460: The blues is usually dated after the Emancipation Act of 1863 , between 1860s and 1890s, a period that coincides with post- emancipation and later, the establishment of juke joints as places where African-Americans went to listen to music, dance, or gamble after a hard day's work. This period corresponds to the transition from slavery to sharecropping, small-scale agricultural production, and
10703-516: The blues narrowly in terms of certain chord structures and lyric forms thought to have originated in West Africa, audiences originally heard the music in a far more general way: it was simply the music of the rural south, notably the Mississippi Delta . Black and white musicians shared the same repertoire and thought of themselves as " songsters " rather than blues musicians. The notion of blues as
10842-459: The blues was rooted in ... the savanna hinterland, from Senegambia through Mali, Burkina Faso, Northern Ghana, Niger, and northern Nigeria". Additionally, ethnomusicologist John Storm Roberts has argued that "The parallels between African savanna-belt string-playing and the techniques of many blues guitarists are remarkable. The big kora of Senegal and Guinea are played in a rhythmic-melodic style that uses constantly changing rhythms, often providing
10981-411: The blues, usually dating back to the middle of the 18th century, when the slaves were Christianized and began to sing and play Christian hymns , in particular those of Isaac Watts , which were very popular. Before the blues gained its formal definition in terms of chord progressions, it was defined as the secular counterpart of spirituals. It was the low-down music played by rural blacks. Depending on
11120-479: The boogie-woogie wave and was strongly influenced by big band music. It uses saxophone or other brass instruments and the guitar in the rhythm section to create a jazzy, up-tempo sound with declamatory vocals. Jump blues tunes by Louis Jordan and Big Joe Turner , based in Kansas City, Missouri , influenced the development of later styles such as rock and roll and rhythm and blues. Dallas-born T-Bone Walker , who
11259-462: The bowl. Ovation developed a thin neck, striving for the feel of an electric guitar's neck, but with additional strength from layers of mahogany and maple reinforced by a steel rod in an aluminum channel. The composite materials and thin necks reduced weight. For its soundboards, Ovation uses Sitka spruce , a wood that Kaman engineers used in helicopter blades. In the 1970s, Ovation developed thinner soundboards with carbon-based composites laminating
11398-464: The casting of cannon, the blast furnace came into widespread use in France in the mid 15th century. The blast furnace had been used in China since the 4th century BC. The stocking frame , which was invented in 1598, increased a knitter's number of knots per minute from 100 to 1000. The Industrial Revolution was the transition to new manufacturing processes in Europe and the United States from 1760 to
11537-512: The company was established. The first Ovation guitar made its debut in November 1966. Its Lyrachord body gave the instrument, according to the company, unprecedented projection and ringing sustain. Compared to modern Ovation Guitars, the initial instruments had a shiny bowl that was used again, for example, in the Balladeer 40th anniversary re-issue. The introduction and promotion of the first Ovation
11676-568: The concept of "focus", with an implication that a business cannot perform at the highest level along all five dimensions and must therefore select one or two competitive priorities. This view led to the theory of "trade offs" in manufacturing strategy. Similarly, Elizabeth Haas wrote in 1987 about the delivery of value in manufacturing for customers in terms of "lower prices, greater service responsiveness or higher quality". The theory of "trade offs" has subsequently being debated and questioned, but Skinner wrote in 1992 that at that time "enthusiasm for
11815-451: The concepts of 'manufacturing strategy' [had] been higher", noting that in academic papers , executive courses and case studies , levels of interest were "bursting out all over". Manufacturing writer Terry Hill has commented that manufacturing is often seen as a less "strategic" business activity than functions such as marketing and finance , and that manufacturing managers have "come late" to business strategy-making discussions, where, as
11954-450: The conventional dreadnought. Once the engineers had settled on a parabolic shape, they turned their attention to developing a substance that could be molded into this bowl-like shape. Using their knowledge of high-tech aerospace composites, they developed Lyrachord, a patented material comprising interwoven layers of glass filament and bonding resin. The first successful design, built by luthier Gerry Gardner, went into production soon after
12093-479: The emphasis and impact of the lyrics, and vocal dramatics using shouts, groans, moans, and wails. The blues women thus effected changes in other types of popular singing that had spin-offs in jazz, Broadway musicals , torch songs of the 1930s and 1940s, gospel , rhythm and blues , and eventually rock and roll ." Urban male performers included popular black musicians of the era, such as Tampa Red , Big Bill Broonzy and Leroy Carr . An important label of this era
12232-429: The expansion of railroads in the southern United States. Several scholars characterize the development of blues music in the early 1900s as a move from group performance to individualized performance. They argue that the development of the blues is associated with the newly acquired freedom of the enslaved people. According to Lawrence Levine, "there was a direct relationship between the national ideological emphasis upon
12371-430: The first copyrighted blues composition. In lyrics, the phrase is often used to describe a depressed mood. Early traditional blues verses often consisted of a single line repeated four times. However, the most common structure of blues lyrics today was established in the first few decades of the 20th century, known as the "AAB" pattern. This structure consists of a line sung over the first four bars, its repetition over
12510-771: The first production solid-body electric-guitars with active electronics , the Ovation Breadwinner . The model did not become popular, however, and production of the Breadwinner and the Ovation Deacon ceased in 1980. Ovation made several other solid-body models up until the mid-1980s. Since that time, the company has focused mainly on acoustic and acoustic-electric guitars. Apart from guitars, Ovation has manufactured other string instruments such as acoustic bass guitars , ukuleles , and mandolins . Comprehensive history Model Manufacturing company Manufacturing
12649-402: The form of choppers or scrapers . These tools greatly aided the early humans in their hunter-gatherer lifestyle to form other tools out of softer materials such as bone and wood. The Middle Paleolithic , approximately 300,000 years ago, saw the introduction of the prepared-core technique , where multiple blades could be rapidly formed from a single core stone. Pressure flaking , in which
12788-535: The form of a loose narrative. African-American singers voiced their "personal woes in a world of harsh reality: a lost love, the cruelty of police officers, oppression at the hands of white folk, [and] hard times". This melancholy has led to the suggestion of an Igbo origin for blues, because of the reputation the Igbo had throughout plantations in the Americas for their melancholic music and outlook on life when they were enslaved. Other historians have argued that there
12927-417: The genre took its shape from the idiosyncrasies of individual performers. However, there are some characteristics that were present long before the creation of the modern blues. Call-and-response shouts were an early form of blues-like music; they were a "functional expression ... style without accompaniment or harmony and unbounded by the formality of any particular musical structure". A form of this pre-blues
13066-481: The globe, manufacturers can be subject to regulations and pollution taxes to offset the environmental costs of manufacturing activities . Labor unions and craft guilds have played a historic role in the negotiation of worker rights and wages. Environment laws and labor protections that are available in developed nations may not be available in the third world . Tort law and product liability impose additional costs on manufacturing. These are significant dynamics in
13205-601: The growth of the ancient civilizations, many ancient technologies resulted from advances in manufacturing. Several of the six classic simple machines were invented in Mesopotamia. Mesopotamians have been credited with the invention of the wheel. The wheel and axle mechanism first appeared with the potter's wheel , invented in Mesopotamia (modern Iraq) during the 5th millennium BC. Egyptian paper made from papyrus , as well as pottery , were mass-produced and exported throughout
13344-505: The high volumes needed in live venues. When he became one of Ovation Guitars' first endorsers, Glen Campbell suggested reducing the weight of the guitar, which he had discovered caused back strain. After that, Ovation reduced the weight of several models and pioneered "super-shallow" guitar bodies. While it was produced, Ovation's super-shallow 1867 Legend was the recommended guitar in Robert Fripp 's Guitar Craft . Tamm (1990) wrote that
13483-454: The huge variety of proto-blues styles, such as field hollers and ring shouts . A record of blues music as it existed before 1920 can also be found in the recordings of artists such as Lead Belly and Henry Thomas . All these sources show the existence of many different structures distinct from twelve- , eight- , or sixteen-bar . The social and economic reasons for the appearance of the blues are not fully known. The first appearance of
13622-582: The increasing shift to electric motors. Electrification enabled modern mass production, and the biggest impact of early mass production was in the manufacturing of everyday items, such as at the Ball Brothers Glass Manufacturing Company , which electrified its mason jar plant in Muncie, Indiana , U.S. around 1900. The new automated process used glass blowing machines to replace 210 craftsman glass blowers and helpers. A small electric truck
13761-434: The individual, the popularity of Booker T. Washington's teachings, and the rise of the blues." Levine stated that "psychologically, socially, and economically, African-Americans were being acculturated in a way that would have been impossible during slavery, and it is hardly surprising that their secular music reflected this as much as their religious music did." There are few characteristics common to all blues music, because
13900-407: The industry in the United States and other countries. According to a "traditional" view of manufacturing strategy, there are five key dimensions along which the performance of manufacturing can be assessed: cost, quality , dependability , flexibility and innovation . In regard to manufacturing performance, Wickham Skinner , who has been called "the father of manufacturing strategy ", adopted
14039-399: The instrument's conventional back and sides with composite synthetic bowls. Kaman felt there were structural weaknesses in the orthogonal joining of the sides, and that a composite material could provide a smooth body. Ovation claims the parabolic bowls dramatically reduce feedback, allowing greater amplification. Improved synthetics techniques from helicopter engineering control vibrations in
14178-405: The large-scale manufacture of machine tools and the use of increasingly advanced machinery in steam-powered factories. Building on improvements in vacuum pumps and materials research, incandescent light bulbs became practical for general use in the late 1870s. This invention had a profound effect on the workplace because factories could now have second and third shift workers. Shoe production
14317-408: The last bars. Early blues frequently took the form of a loose narrative, often relating the racial discrimination and other challenges experienced by African-Americans. Many elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa . The origins of the blues are also closely related to the religious music of the African-American community,
14456-586: The low rate of literacy among rural African Americans at the time. Reports of blues music in southern Texas and the Deep South were written at the dawn of the 20th century. Charles Peabody mentioned the appearance of blues music at Clarksdale, Mississippi , and Gate Thomas reported similar songs in southern Texas around 1901–1902. These observations coincide more or less with the recollections of Jelly Roll Morton , who said he first heard blues music in New Orleans in 1902; Ma Rainey , who remembered first hearing
14595-704: The market towards end customers . This relative cost reduction towards the market, is how manufacturing firms secure their profit margins . Manufacturing has unique health and safety challenges and has been recognized by the National Institute for Occupational Safety and Health (NIOSH) as a priority industry sector in the National Occupational Research Agenda (NORA) to identify and provide intervention strategies regarding occupational health and safety issues. Surveys and analyses of trends and issues in manufacturing and investment around
14734-516: The music industry during the 1920s and 1930s. Other chord progressions, such as 8-bar forms, are still considered blues; examples include " How Long Blues ", " Trouble in Mind ", and Big Bill Broonzy 's " Key to the Highway ". There are also 16-bar blues , such as Ray Charles 's instrumental "Sweet 16 Bars" and Herbie Hancock 's " Watermelon Man ". Idiosyncratic numbers of bars are occasionally used, such as
14873-452: The next four, and a longer concluding line over the last bars. This pattern can be heard in some of the first published blues songs, such as " Dallas Blues " (1912) and " Saint Louis Blues " (1914). According to W.C. Handy , the "AAB" pattern was adopted to avoid the monotony of lines repeated three times. The lyrics are often sung in a rhythmic talk style rather than a melody, resembling a form of talking blues . Early blues frequently took
15012-423: The ongoing process, occurring over the last few decades, of manufacture-based industries relocating operations to "developing-world" economies where the costs of production are significantly lower than in "developed-world" economies. From a financial perspective, the goal of the manufacturing industry is mainly to achieve cost benefits per unit produced, which in turn leads to cost reductions in product prices for
15151-615: The period, such as the increasing adoption of locomotives, steamboats and steamships, hot blast iron smelting and new technologies, such as the electrical telegraph , were widely introduced in the 1840s and 1850s, were not powerful enough to drive high rates of growth. Rapid economic growth began to occur after 1870, springing from a new group of innovations in what has been called the Second Industrial Revolution . These innovations included new steel making processes , mass-production , assembly lines , electrical grid systems,
15290-517: The production flow and some had special carriages for rolling heavy items into machining positions. Production of the Ford Model T used 32,000 machine tools. Lean manufacturing , also known as just-in-time manufacturing, was developed in Japan in the 1930s. It is a production method aimed primarily at reducing times within the production system as well as response times from suppliers and to customers. It
15429-489: The propulsive left-hand rhythms of the ragtime pianists with melodic figures similar to those of Armstrong's trumpet in the right hand". The smooth Louisiana style of Professor Longhair and, more recently, Dr. John blends classic rhythm and blues with blues styles. Another development in this period was big band blues. The " territory bands " operating out of Kansas City , the Bennie Moten orchestra, Jay McShann , and
15568-458: The religious community a musician belonged to, it was more or less considered a sin to play this low-down music: blues was the devil's music. Musicians were therefore segregated into two categories: gospel singers and blues singers, guitar preachers and songsters. However, when rural black music began to be recorded in the 1920s, both categories of musicians used similar techniques: call-and-response patterns, blue notes, and slide guitars. Gospel music
15707-494: The same time, Ovation provided small doors that blocked the sound holes from the inside in order to dampen feedback in the presence of loud stage monitors. Gypsy had also requested the addition of a round hatch in the back of the body of pre-Adamas guitars to facilitate changing the on-board battery, a feature that was then adopted for all the "round holes." Before this time, the strings on the round-hole guitars had to be removed to do this. On-board electronics let guitarists move about
15846-439: The sides. The innovation was the use of a thinner, synthetic back, because of its foreseen acoustic properties. Unfortunately, the seam joining the sides to the thin back was prone to breakage. To avoid the problem of a structurally unstable seam, the engineers proposed a synthetic back with a parabolic shape. By mid-1966, according to Ovation, they realized that the parabolic shape produced a desirable tone with greater volume than
15985-460: The single direct ancestor of the blues. However the call-and-response format can be traced back to the music of Africa . That blue notes predate their use in blues and have an African origin is attested to by "A Negro Love Song", by the English composer Samuel Coleridge-Taylor , from his African Suite for Piano , written in 1898, which contains blue third and seventh notes . The Diddley bow (a homemade one-stringed instrument found in parts of
16124-406: The southeastern "delicate and lyrical" Piedmont blues tradition, which used an elaborate ragtime-based fingerpicking guitar technique. Georgia also had an early slide tradition, with Curley Weaver , Tampa Red , "Barbecue Bob" Hicks and James "Kokomo" Arnold as representatives of this style. The lively Memphis blues style, which developed in the 1920s and 1930s near Memphis, Tennessee ,
16263-850: The stage rather than stay in front of a microphone. On-board electronic tuning, availability, uniformity, and frugal costs facilitated performances by guitar ensembles like Robert Fripp 's Guitar Craft students. Ovation has also produced solid-body electric guitars and active basses . Ovations reached the height of their popularity in the 1980s, where they were often seen during live performances by touring artists, such as Rush 's Alex Lifeson or Paul Simon in The Concert in Central Park . Ovation guitars' synthetic bowl-shaped back and early use (1971) of pre-amplifiers , onboard equalization and piezo pickups were particularly attractive to live acoustic musicians who constantly battled feedback problems from
16402-567: The standard model range of Ovation guitars in the U.S. had been ceased under the ownership of Fender Musical Instruments Corporation , but is planned to be reinstated by the new owner Drum Workshop . The Adamas name mainly stands for guitars with a carbon fiber top, although there are exceptions (one is the Adamas 2081WT - WT stands for woodtop). Until the closure of the New Hartford, Connecticut factory in June 2014, all Adamas models were produced in
16541-466: The term "blues" was associated with drinking alcohol, a meaning which survives in the phrase ' blue law ', which prohibits the sale of alcohol on Sunday. In 1827, it was in the sense of a sad state of mind that John James Audubon wrote to his wife that he "had the blues". In Henry David Thoreau 's book Walden , he mentions "the blues" in the chapter reflecting on his time in solitude. He wrote his account of his personal quest in 1845, although it
16680-465: The term in this sense is in George Colman 's one-act farce Blue Devils (1798). The phrase 'blue devils' may also have been derived from a British usage of the 1600s referring to the "intense visual hallucinations that can accompany severe alcohol withdrawal". As time went on, the phrase lost the reference to devils and came to mean a state of agitation or depression. By the 1800s in the United States,
16819-437: The then-well-known technique of chain or sequential production. Ford also bought or designed and built special purpose machine tools and fixtures such as multiple spindle drill presses that could drill every hole on one side of an engine block in one operation and a multiple head milling machine that could simultaneously machine 15 engine blocks held on a single fixture. All of these machine tools were arranged systematically in
16958-446: The trance-like rhythm and call-and-response, and they form a repetitive effect called a groove . Characteristic of the blues since its Afro-American origins, the shuffles played a central role in swing music . The simplest shuffles, which were the clearest signature of the R&;B wave that started in the mid-1940s, were a three-note riff on the bass strings of the guitar. When this riff
17097-431: The world focus on such things as: In addition to general overviews, researchers have examined the features and factors affecting particular key aspects of manufacturing development. They have compared production and investment in a range of Western and non-Western countries and presented case studies of growth and performance in important individual industries and market-economic sectors. On June 26, 2009, Jeff Immelt ,
17236-469: Was Charles McDonough, who created the Ovation Adamas model. Kaman founded Ovation Instruments, and in 1965 its engineers and luthiers (guitar makers) worked to improve acoustic guitars by changing their conventional materials. The R&D team spent months building and testing prototype instruments. Their first prototype had a conventional "dreadnought" body , with parallel front and back perpendicular to
17375-532: Was a formally trained musician, composer and arranger who helped to popularize the blues by transcribing and orchestrating blues in an almost symphonic style, with bands and singers. He became a popular and prolific composer, and billed himself as the "Father of the Blues"; however, his compositions can be described as a fusion of blues with ragtime and jazz, a merger facilitated using the Cuban habanera rhythm that had long been
17514-499: Was closely associated with two performing artists, the blues -performer Josh White and the country-music singer Glen Campbell . In 1966–1967, the Ovation Guitar Company produced a signature guitar for Josh White, which was the first signature guitar made for an African American. White was the first official Ovation endorser. Upon completion, the first Ovation guitar was called the "Josh White Model," which White played at
17653-399: Was closely related to ragtime , which developed at about the same time, though the blues better preserved "the original melodic patterns of African music". The musical forms and styles that are now considered the blues as well as modern country music arose in the same regions of the southern United States during the 19th century. Recorded blues and country music can be found as far back as
17792-457: Was heard in slave ring shouts and field hollers , expanded into "simple solo songs laden with emotional content". Blues has evolved from the unaccompanied vocal music and oral traditions of slaves imported from West Africa and rural blacks into a wide variety of styles and subgenres, with regional variations across the United States. Although blues (as it is now known) can be seen as a musical style based on both European harmonic structure and
17931-567: Was influenced by jug bands such as the Memphis Jug Band or the Gus Cannon's Jug Stompers . Performers such as Frank Stokes , Sleepy John Estes , Robert Wilkins , Kansas Joe McCoy , Casey Bill Weldon and Memphis Minnie used a variety of unusual instruments such as washboard , fiddle , kazoo or mandolin . Memphis Minnie was famous for her virtuoso guitar style. Pianist Memphis Slim began his career in Memphis, but his distinct style
18070-833: Was introduced in Australia in the 1950s by the British Motor Corporation (Australia) at its Victoria Park plant in Sydney, from where the idea later migrated to Toyota. News spread to western countries from Japan in 1977 in two English-language articles: one referred to the methodology as the "Ohno system", after Taiichi Ohno , who was instrumental in its development within Toyota. The other article, by Toyota authors in an international journal, provided additional details. Finally, those and other publicity were translated into implementations, beginning in 1980 and then quickly multiplying throughout
18209-476: Was mechanized during the mid 19th century. Mass production of sewing machines and agricultural machinery such as reapers occurred in the mid to late 19th century. The mass production of bicycles started in the 1880s. Steam-powered factories became widespread, although the conversion from water power to steam occurred in England earlier than in the U.S. Electrification of factories, which had begun gradually in
18348-659: Was nevertheless using musical forms that were compatible with Christian hymns and therefore less marked by the blues form than its secular counterpart. The American sheet music publishing industry produced a great deal of ragtime music. By 1912, the sheet music industry had published three popular blues-like compositions, precipitating the Tin Pan Alley adoption of blues elements: "Baby Seals' Blues", by Baby Franklin Seals (arranged by Artie Matthews ); "Dallas Blues", by Hart Wand ; and " The Memphis Blues ", by W.C. Handy . Handy
18487-474: Was not published until 1854. The phrase "the blues" was written by Charlotte Forten , then aged 25, in her diary on December 14, 1862. She was a free-born black woman from Pennsylvania who was working as a schoolteacher in South Carolina, instructing both slaves and freedmen, and wrote that she "came home with the blues" because she felt lonesome and pitied herself. She overcame her depression and later noted
18626-483: Was now used to handle 150 dozen bottles at a time whereas previously used hand trucks could only carry 6 dozen bottles at a time. Electric mixers replaced men with shovels handling sand and other ingredients that were fed into the glass furnace. An electric overhead crane replaced 36 day laborers for moving heavy loads across the factory. Mass production was popularized in the late 1910s and 1920s by Henry Ford 's Ford Motor Company , which introduced electric motors to
18765-420: Was played over the bass and the drums, the groove "feel" was created. Shuffle rhythm is often vocalized as " dow , da dow , da dow , da" or " dump , da dump , da dump , da": it consists of uneven, or "swung", eighth notes. On a guitar this may be played as a simple steady bass or it may add to that stepwise quarter note motion from the fifth to the sixth of the chord and back. Hart Wand 's " Dallas Blues "
18904-430: Was published in 1912; W.C. Handy 's " The Memphis Blues " followed in the same year. The first recording by an African American singer was Mamie Smith 's 1920 rendition of Perry Bradford 's " Crazy Blues ". But the origins of the blues were some decades earlier, probably around 1890. This music is poorly documented, partly because of racial discrimination in U.S. society, including academic circles, and partly because of
19043-507: Was replaced by the term rhythm and blues . This rapidly evolving market was mirrored by Billboard magazine's Rhythm & Blues chart . This marketing strategy reinforced trends in urban blues music such as the use of electric instruments and amplification and the generalization of the blues beat, the blues shuffle , which became ubiquitous in rhythm and blues (R&B). This commercial stream had important consequences for blues music, which, together with jazz and gospel music , became
19182-444: Was smoother and had some swing elements. Many blues musicians based in Memphis moved to Chicago in the late 1930s or early 1940s and became part of the urban blues movement. City or urban blues styles were more codified and elaborate, as a performer was no longer within their local, immediate community, and had to adapt to a larger, more varied audience's aesthetic. Classic female urban and vaudeville blues singers were popular in
19321-536: Was the Chicago-based Bluebird Records . Before World War II, Tampa Red was sometimes referred to as "the Guitar Wizard". Carr accompanied himself on the piano with Scrapper Blackwell on guitar, a format that continued well into the 1950s with artists such as Charles Brown and even Nat "King" Cole . Boogie-woogie was another important style of 1930s and early 1940s urban blues. While the style
